What does it mean when the clip I’ve selected is “letterboxed”?
If the shot you have selected is “letterboxed”, this means it was shot for wide screen usage. We can alter the aspect ratio of a wide screen shot to match the standard 4:3 television size at your request. Conversely, we can also alter standard 4:3 shots to a wide screen aspect ratio, though sometimes this does present difficulties and can affect the ultimate quality of the shot.Although this is not recommended.
